Method of compensating for the reduction in flow rate of an internal combustion engine injector

摘要

This method applies to injection systems where the flow rate of the injector, proportional to its open time controlled by an electronic computer, has a predetermined relationship with the filling of the engine with air and its idling rate is adjustable by means of a manual adjusting device. The computer periodically compares the adjusted value VALPOT of the said device with a predetermined threshold value DPOT and, when the threshold value is exceeded by the manually adjusted value, modifies the open time Ti of the injector as a function of the said adjusted value VALPOT of the device, according to an experimentally determined law in order to maintain substantially unchanged the said predetermined relationship DELTA between the fuel flow rate Q and the filling of the engine with air R.
